WA live-export activists pelted with eggs

Eggs were thrown and a woman carrying a child jumped in front of a truck as anti live-export demonstrators and farmers held duelling rallies in Fremantle.

Stop Live Exports co-ordinator Katrina Love said about 1000 people formed a human chain across Stirling Bridge on Sunday morning, up from 370 last year.

At the same time, about 900 farmers, breeders and live export industry workers held a rally on the foreshore below as a procession of about a dozen trucks, plastered with banners in support of the trade, drove across the bridge.

Ms Love said the protest was largely peaceful, but a handful of demonstrators - including a woman carrying a child - jumped in front of the trucks in an effort to stop them.

She said she did not condone those actions and the protesters would have been instructed to make a more symbolic gesture if police had warned organisers about the convoy.

"We could have asked everyone to turn their backs to the trucks, which would have been more poignant," Ms Love told AAP.

She said eggs were hurled at demonstrators - presumably by people in support of the live export trade - from passing cars.
